Hello
I'm one of the French students (so please excuse my bad English...) who are working on this projects.
Before presenting the project, I want to say that we are not student in a terrain generation course. In fact our school is teaching us general programming skills (this year oop [java], os an d compilation). Beside, we had to do a "Projet de science de l'ingénieur" (translate into something like : Engineering's skills project). We love Tremulous (but are not very good gamers) and we have an ex professor who happens to like it too. So after a little bit of brainstorming we decided to launch ourselves into this projects.
So what is the project ?
We are trying to do random map generation for tremulous. It's just a bunch of C++ sources which generating a .map file. We compile it/package it into a pk3 and "hop a new map". That was for the theory. At the moment, we have terrain generator, a forest generator, some water, and an algorithm to lay some objects in the map.
In the future we'd plan to have a room and corridor / alien-tunnels generator.
We certainly will be shortly in need of testers (we are not really skilled at playing tremulous [too much coding

] ), artwork and help in mastering shaders. A web page presenting the project will be available soon (and better written, I do hope!).
So Stay tuned!!
